Making menus

The \htmlmenu command generates a menu for the subsections of a
section. Its argument is the depth of the desired menu. If you use
\htmlmenu{2} in a subsection, say, you will get a menu of all
subsubsections and paragraphs of this subsection.

If you use this command in a section, no automatic
menu for this section is created.

A typical application of this command is to put a "master menu" (the
analog of a table of contents) in the top node,
containing all sections of all levels of the document. This can be
achieved by putting \htmlmenu{6} in the text for the top node.

You can create a menu for a section other than the current one by
passing the number of that section as the optional argument, as in
\htmlmenu[0]{6}, which creates a full table of contents. (The
optional argument uses Hyperlatex's internal numbering-not very
useful except for the top node, which is always number 0.)

Some people like to close off a section after some subsections of that
section, somewhat like this:
